Secondary Containment Tanks

Secondary Containment tanks are also referred to as open top containment tanks, spill containment tanks, containment trays, and containment basins. They are often used in the agricultural, industrial, manufacturing, and commercial sectors. These tanks can be used to store chemicals, fertilizer, and even potable water since they are made from FDA approved polyethylene.

These secondary containment tanks are also commonly used to house vertical, horizontal, or cone bottom tanks within them. In case of primary tank failure, the secondary containment tank capacity should be greater than that of the primary tank. In this way, the containment tank serves as a barrier between the interior tank and the outside world. This barrier prevents any leaks, spills, or liquid overflows from the main tank from causing groundwater contamination or damaging the surrounding environment or equipment. Because liquids are safely held within the tank, cleanup is quick and simple.

Containment tanks are manufactured by Norwesco and Ace Roto-Mold / Den Hartog. High density virgin polyethylene resin is rotationally molded into these seamless containment basins. These plastic tanks are resistant to rust, corrosion, and impact. The UV inhibitors added during production make them resistant to sun degradation, too. They are capable of withstanding a wide range of temperatures and weather conditions, so they can be used indoors or outdoors all year round. Containment tanks have flat bottoms, so they do not require additional structural support.

These lightweight, plastic containment tanks are easy to move and offer a more affordable alternative to double walled tanks or concrete containment structures. Containment tanks are available in colors of transparent white or opaque black or green. They come in a variety of dimensions and capacities ranging from 140 gallons up to 6800 gallons. National Tank Outlet offers custom containment tank fabrication for clients desirous of any size not already readily available. To assist with drainage, manufacturers will add fittings to the containment tank when requested. All containment tanks come with a 3 year manufacturer’s warranty.
